Our inground pool has slate tiles surrounding it and set in concrete.
The concrete had cracked and chipped out. We mixed up new concrete patch
and filled in the voids. We didn't do it neatly and now have concrete
residue on the slate. It's mainly a film. Whats the best way to clean
this up. It's been a week since we did the job. Thanks for your help

I'd try wiping it with vinegar, acid is usually the ticket for cleaning
up concrete

You can buy hydrochloric acid based product to remove this.

There's a product used to remove mortar skim from tile that may help. Check
your local tile store for "Grout Haze Remover." Most contain Sulfamic acid.

Check:

Muriatic acid is used to clean concrete ( more eating a layer off) ,
you might try a small spot, read up on it it will burn you bad. Not
sure what the effect would be on slate.
